Calla lily plant named ‘Dozansuny’

ABSTRACT

‘Dozansuny’ is a new variety of calla lily plant having yellow colored spathes that produces 4-7 inflorescences per 16-18 cm tuber. The flower stems are about 25-34.5 cm in height. The leaves are dark green with maculations present and a smooth texture.

Botanical classification: Zantedeschia sprengeri.

Varietal denomination: ‘Dozansuny’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of callalily, botanically known as Zantedeschia sprengeri and hereinafterreferred to by the varietal name ‘Dozansuny’. ‘Dozansuny’ is a productof a planned breeding program, which had the objective of creatingZantedeschia hybrids for pot flower production in a wide range of colorswith a classic flower shape. The new cultivar is a seedling selectedfrom the crossing of Zantedeschia sprengeri seedling Z041943-887 (femaleparent, unpatented) with Zantedeschia sprengeri variety ‘Fursa’ (maleparent, U.S. Plant Pat. No. 29,119). ‘Dozansuny’ was selected in 2014 bythe inventor in 't Zand, The Netherlands as one flowering plant withinthe progeny of the stated cross.

The first act of asexual reproduction of ‘Dozansuny’ by tissue culturewas performed by the inventor in November of 2014 in 't Zand, TheNetherlands. Subsequent asexual reproductions by tissue culture at thesame location have demonstrated that the combination of characteristicsas herein disclosed for the new cultivar are retained and reproducedtrue to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plantsat approximately 9 weeks from planting in 14 cm pots in 't Zand, TheNetherlands under greenhouse conditions, which approximate thosegenerally used in horticultural practice. Color references are made toThe 2001 R.H.S. Colour Chart of The Royal Horticultural Society ofLondon, 4^(th) Edition, except where general color terms of ordinarysignificance are used.

The present invention has not been evaluated under all possibleenvironmental conditions. The phenotype may vary with variations inenvironment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to bebasic characteristics of ‘Dozansuny’ which, in combination, distinguishthis calla lily as a new and distinct cultivar:

-   -   1. Medium yellow colored spathes without a throat spot;    -   2. Dark green colored leaves; and    -   3. Few leaf maculations present.

The new variety is similar to its female parent. in the followingtraits: spathe, spadix, and stein color, leaf shape, and the presence ofleaf maculations. However, ‘Dozansuny’ exhibits a broader spathe width,longer spathe and spadix length, and more leaf maculations than itsfemale parent. Further, its female parent has a spathe throat spot. Thenew variety is similar to its male parent in the following traits:spathe and stern color, leaf shape, and the presence of leafmaculations. However, ‘Dozansuny’ exhibits a broader spathe width,longer spathe and spadix length, weaker flower curve, and fewer leafmaculations than its male parent. Further, its male parent has a spathethroat spot and a yellow orange colored spadix.

When compared to calla lily plant named ‘Yellow Jacket BLZ’ (U.S. PlantPat. No. 20,217), the upper surface spathe color is similar, but thelower surface spathe color of ‘Yellow Jacket BLZ’ is Yellow Group RHS7B.
